APPARATUS FOR EVAPORATING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 568,615, dated September 29, 1896. Application filed June 8, 1896. Serial No. 594,704. (No model.)

T 0 aZZ whom it nm-y concern:

Be it known that I, LEON FRANCOIS HAUBT- MAN, of New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and Improved Apparatus for Evaporating Liquids, of which the following is a full, clear, and exact description.

The object of this invention is to provide a very simple and comparatively inexpensive apparatus for the purpose described and in which the material is condensed as it passes in a thin film or sheet through long lengths of tubing.

I will describe an apparatusembodying my inventionand then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawing, forming a part of this specification, in which the figure is a vertical section of an apparatus embodying my invention.

The apparatus comprises a casing 1, which may be cylindrical or angular in cross-section, as desired. It has a diaphragm 2 in its upper portion, which forms the bottom of a liquid-receiver 3, and a diaphragm 4, located in the lower portion of the casing, forms the top of an absorbing-chamber 5, the bottom of this absorbing chamber 5 being funnel shaped and having communication by means of a valve-controlled pipe 6 with a receiver 7 for the condensed liquid or liquor.

' Oommunicatingwit-h the receiver 3 through a valve-controlled pipe 8 is a receptacle 9 for Arranged in the bottom of this receptacle 9 is a series of steampipes 10, which may receive steam from any desired source. A valve-controlled steaminlet pipe 11 leads into the upper portion of the casing 1, and a valve-controlled outletpipe 12 leads outward from the lower portion of said casing. 7 Extended vertically in the casing is a series of tubes 13, having their lower ends extended through the diaphragm 4, so as to provide communication with the evaporating-chamber 5, and having their upper ends extended through the diaphragm 2 and somewhat above the upper side of said diaphragm and into the receiver 3. It will also be seen that the upper ends of these pipes are above the plane of the inlet 11.

A pump 14 is here shown for the purpose of returning material or liquid from the receiver 7 to the receptacle 9, should it be required to treat the liquid a second time. This pump has a pipe connection 15 with the receiver 7 and a pipe connection 16 with the receptacle 9, and both of these pipes are provided with suitable valves.

An air-heater 17, comprising a series of steam pipes communicating with steamchambers at the ends of the heater-casin g, has communication with the chamber 5 through a pipe 18, and this heater at its lower side is in communication with a fan or blower 19. This heater is similar in construction to the heater shown in my patent application, Serial No. 546,530, of September 17, 1895, and therefore need not be particularly described. It may be stated, however, that steam is led into the heater through the valve-controlled pipe 20 and led oif or condensed through the valve-controlled pipe 21.

The operation is as follows: The receptacle 9 being full of liquor to be condensed, steam is admitted to said receptacle and also to the interior of the casing or drum 1 to circulate around the pipes 13 in said casing or drum. After the liquid flowing from the receptacle 9 into the receiver 3 shall have reached a level with the upper ends of the pipes 13 the liquid will flow downward through said pipes in thin sheets against the inner surfaces of the pipes 13. At the same time the heated air will be forced upward through said pipes 13, as indicated by the arrows, and in its course will absorb the greater portion of the moisture from the liquor. The inlet of the pipe 18, leading into the absorbing-chamber 5, is provided with a perforated plate 22, which will separate the inflowing air into small streams and distribute it thoroughly in'the chamber 5, so that it will absorb moisture from the liquor flowing into said chamber.

The liquors to be treated may be condensed to any desired degree, and all liquor not properly or thoroughly condensed can be forced back into the receptacle 9 by means of the pump let and then treated to a second operation. The steam in the casing or drum 1 and surrounding the pipes 13 will thoroughly heat said pipes, which will aid materially in forcing the moisture from the liquid flowing through the pipes.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent-- 1. An apparatus for evaporating liquids, comprising a drum or casing, a series of pipes arranged vertically therein and comm unicating at their upper ends with a receiver and communicating at their lower ends with an absorbing-chamber, the upper ends of said pipes being extended above the bottom of the receiver, a receptacle for liquid to be treated, having communication with the receiver be low the upper ends of the vertical pipes, a heater, means for forcing air through said heater and into the absorbing-chamber, and a perforated plate for distributing the air in said absorbingchamber, substantialiy as specified.

2. An apparatus for evaporating liquids, comprising a drum or casing having a diaphragm in its upper portion, forming the bottom of a receiver, a diaphragm in its lower portion, forming the top of an absorbingchamber, pipes within the drum or casing leading through said diaphragm, the upper ends of said pipes projecting above the top of the upper diaphragm, a receptacle for liquid to be treated, having communication with the receiver, steam heating-pipes arranged in said receptacle, a heater, a blower for forcing air through said heater, a pipe connection between said heater and the absorbing-chamber, a perforated plate through which the air from said pipe is forced, a tank for receiving the condensed. liquid, and a pump for forcing liquid from said tank to the receptacle, substantially as specified.
